larry, back to you. >> many thanks, steve handelsman, appreciate it. so why has general petraeus done a 180 on benghazi? this is a very serious issue. first he blames the attack on a video. now he's saying it was a terrorist attack and the briefing notes were changed. something doesn't add up. here now is michael rubin, resident scholar at the american enterprise institute, and alexis levinson, reporter at the daily quarter. michael, i'll go to you first. peter king himself today, i guess i'll quote this, he said that the testimony petraeus gave today, that they knew immediately it was a terrorist attack, differed with his own briefing to lawmakers on september 14th. sources say that petraeus somehow has chaud hnged his position. now, i don't get this. before i even get to the talking points, michael, how can petraeus say one thing on september 14th and then come back today and say no, no, no, here's what really happened, we knew about it all the time? >> you know, larry, that's an excellent question. but this is what really gets me. president obama, w
